Lasik
surgery alternatives
There are many people who unfortunately are not eligible for
LASIK surgery, but there are alternative treatments that can
help them. One technique is not necessarily better than the
other, but certain types can be more effective for some unique
problems. All the treatments have the same goal, to change the
shape of the cornea and correct vision problems. All the
procedures for vision correction are going to involve
manipulating underneath the outer layer of tissue on the
cornea, and the epithelium on the surface of the eye.
LASEK
LASEK, which stands for laser assisted subepithelial
keratomileusis, is one of the most recent treatments designed
for vision correction. It is utilized on patients who have
thinner corneas because the surgery does not remove as much
tissue as LASIK. LASEK is almost identical to LASIK except that
a thinner corneal flap is required to do the procedure.
By using less cornea tissue to create the flap, a surgeon
utilizing the LASEK procedure can leave the tissue under the
flap thicker. This is done by using chemicals to decrease the
bond between tissue layers and creating the flap. Then the
laser is used just as it would in a LASIK surgery. LASEK is
generally done in just one eye at a time, making the time it
takes to recover, longer.
PRK
Photo refractive keratectomy or PRK, is another alternative
treatment that pre-dates LASIK surgery. While LASIK surgery
involves less pain and a faster recovery period, PRK is still a
very effective solution to vision correction. PRK is a valid
option when the corneal flap cannot be produced mechanically or
chemically for whatever reason. In PRK surgery, a surgeon will
manually remove the epithelial tissue. PRK is also done one eye
at a time making its recovery longer than LASIK. It has the
longest recovery of all the refractive procedure options.
Intraocular Implants
Some patients may opt for having intraocular implants. The
procedure is basically like cataract removal involving the
placement of clear intraocular implants. The lens is removed
and replaced by an external implant. This procedure is
especially effective for farsightedness.
Conductive Keratoplasty Then there is conductive
keratoplasty, CK, which is when energy from radio frequencies
is applied to the cornea's periphery in a circular motion. The
heat generated will shrink the tissue of the cornea, which will
cause it to be steeper and correct farsightedness.
